Dome rooflights in Peterborough: what is involved?
We handle dome rooflights across Cambridgeshire, including Peterborough. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Coastal towns in the East of England see salty air, so we specify frame finishes and fixings with exposure in mind. In Peterborough, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We cover all of Peterborough and the PE1 district, and nearby Stamford and Oundle.
Specification options
- Fall-through protection mesh
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Light, impact-resistant domes
- Smoke-vent versions available
Before you order: points to check
- Fire classification matters on some roofs
- Old domes may be fragile — treat as fragile until checked
Building control and safety duties in Peterborough
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Peterborough: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
How do I book a survey in Peterborough?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Peterborough?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
